Answer:
7.2 x 10⁻⁶N
Explanation:
Given parameters:
Mass of Venus = 4.87 x 10²⁴kg
Radius = 6.05 x 10⁶km = 6.05 x 10⁹m
Mass of person = 81kg
Unknown:
Gravitational force = ?
Solution:
To solve this problem, we use the Newtons law of universal gravitation:
Fg =
G is the universal gravitation constant = 6.67 x 10⁻¹¹
Fg =
Fg = 7.2 x 10⁻⁶N
Answer:
Optical fibers are used most often as a means to transmit light between the two ends of the fiber and find wide usage in fiber-optic communications, where they permit transmission over longer distances and at higher bandwidths (data rates) than wire cables.
